Our Anniversaries (1855-1955) (1930-1955)
Get PDFThe current issue of the CONCORDIA THEOLOGICAL MONTHLY greets our readers in festive colors. There is ample reason for donning holiday dress. The year that is drawing to a close marks two milestones in its career. As the direct lineal descendant of Lehre und Wehre (1855) our journal is observing its one-hundredth birthday: It bears the marks of age and the changes that come with growing old. In its younger days it spoke to its readers in the language of Luther as Lehre und Wehre and continued to do so for many years. Also in German the homiletical section had appeared as a separate publication known as Magazin fűr Ev.-Luth. Homiletik
A Sub-Threshold Low-Power Integrated Bandpass Filter for Highly-Integrated Spectrum Analyzers
Get PDFLow-power analog filter banks provide frequency analysis with minimal space requirements, making them viable solutions for integrated remote audio- and vibration-sensing applications. In order to achieve a balance between the length of deployable service and system performance, a critical requirement of such remote sensor networks is low-power consumption, due to the constraints imposed by on-board battery cells.
In this work, the design and implementation of a sub-threshold complementary metal-oxide semiconductor (CMOS) integrated low-power tunable analog filter channel for Oak Ridge National Laboratory is presented. Project specifications required a tunable, high-order, monolithic bandpass filter channel with small chip area and low power consumption. With initial design focusing on the audio frequency spectrum, the 8th [eighth] order filter channel presented in this work provides an effective Q-factor of 4.5 and a minimum dynamic range (DR) of approximately 85 dB, while allowing for tuning across a range of center frequencies from 2 kHz to 100 kHz, with power-consumption of a single 8th order filter channel measured at 155 μW [micro], nominally. An integrated analog Gm-C [transconductance-capacitance] filter topology was selected for this application. Functionally, the high-Q bandpass filter transfer function is implemented via four cascaded filter cells, resulting in a single 8th order filter channel, fabricated in 130-nm 1.2 V CMOS technology, suitable for use in monolithic integrated spectral analysis applications
Grace of God in the Old Testament (Concluded)
Get PDFAfter making a rapid survey of the terms that the Old Testament employs to denote the grace of God, we need to say that these words are not the fleeting sound of empty vocables. Nor do they describe an abstraction in the nature of a Platonic idea. They tell what God does to save men from the curse of their separation from Him and to bring them a life in blessed communion with Him. Our next task is, therefore, to trace how the grace of God entered the lives of the Old Testament believers to bring them salvation
